Dura-Line 20030071 is a DuraFit end plug for 10 mm micro-duct in yellow, used to seal an unused or spare duct against ingress of dust, moisture and pests before or after cable blowing. The push-fit design mates with the standard DuraFit connector interface and can be removed for later cable installation. Typical use is FTTH and telecom micro-duct networks where duct identification is by colour.
